Preparation Phase & Tools to Use

Before diving into the ingredients, let’s talk tools. Having the right equipment not only simplifies the process but also ensures even cooking and the best texture.

• 9×13-inch Baking Dish: Essential for creating those clean, sliceable squares. The size helps the casserole bake evenly without drying out.
• Mixing Bowls: One for whisking the eggs, one for combining dry ingredients, and one for your sausage mix. Keeping them separate avoids clumps and ensures a smooth mix.
• Whisk & Spatula: A whisk helps you get fluffy, evenly combined eggs, while a silicone spatula is perfect for folding and scraping without wasting batter.
• Skillet or Frying Pan: Needed for browning the sausage. Go for a non-stick or cast iron to get that beautiful crisp.
• Measuring Cups and Spoons: Accurate measurements are key when you’re balancing wet and dry ingredients for the perfect bake.

Having everything ready before you start makes the assembly quick and the process enjoyable. Let’s get cooking!

Ingredients for the Sausage Breakfast Casserole

Each ingredient plays a role in building flavor and texture:

• Ground Breakfast Sausage: The savory, spiced heart of the casserole. It gives the dish its meaty depth and comfort.
• Eggs: They bind everything together while giving that fluffy structure we all love in a breakfast bake.
• Shredded Cheddar Cheese: Melts beautifully through the layers, adding richness and golden tops.
• Whole Milk: Softens the mixture and balances the richness with a smooth texture.
• Cornbread Mix: Adds that tender, slightly sweet base and gives the casserole its structure.
• Sweet Corn Kernels: Adds juicy bursts of flavor and texture to cut through the richness.
• Chopped Green Onions or Chives: For a fresh, mild onion bite and color.
• Salt and Pepper: Essential to enhance all the other flavors.

How To Make the Sausage Breakfast Casserole

Step 1: Brown the Sausage

In a skillet over medium heat, cook the ground sausage until browned and crumbled. Drain any excess fat and set aside to cool slightly.

Step 2: Mix the Cornbread Base

In a mixing bowl, combine the cornbread mix with eggs and milk according to package instructions. This forms your casserole base.

Step 3: Layer the Ingredients

Grease your 9×13-inch baking dish. Spread half the cornbread batter into the bottom. Top with the browned sausage, followed by sweet corn, and half the shredded cheese.

Step 4: Add Egg Mixture

In another bowl, whisk the eggs with a pinch of salt and pepper. Pour the egg mixture evenly over the layered casserole.

Step 5: Top and Bake

Add the remaining cornbread batter and top with the rest of the shredded cheese. Bake at 375°F (190°C) for 35–40 minutes, or until the top is golden and a knife inserted in the center comes out clean.

Step 6: Rest and Garnish

Let it rest for 10 minutes before slicing. Sprinkle with chopped chives or green onions.

How to Serve and Store This Casserole

This casserole is best served warm, straight from the oven, with a side of fruit or a dollop of sour cream. For a brunch spread, pair it with a crisp salad or roasted potatoes.

To store leftovers, allow the casserole to cool completely. Cover and refrigerate for up to 4 days. You can reheat individual portions in the microwave or warm the whole dish in the oven at 300°F until heated through.

It also freezes well—wrap slices individually for quick, satisfying breakfasts on busy mornings.
